AF/ArmaFlex Class O is the professional, highlyflexible, closed-cell elastomeric foam insulation (FEF) for continuous energy saving and condensation control purposes. The combination of very low thermal conductivity and extremely high resistance to water vapour transmission prevents long-term energy losses and water vapour ingress and reduces the risk of corrosion under insulation. For the placing on the market of the product in the European Union/European Free Trade Association (EU/EFTA) (with the exception of Switzerland) Regulation (EU) No. 305/2011 (CPR) applies. The product needs a declaration of performance taking into consideration EN 14304:2013-04: Thermal insulation products for building equipment and industrial installations – Factory made flexible elastomeric foam (FEF) products – Specification and the CE-marking. For the application and use the respective national provisions apply.
